I'm trying to typeset the following equation, but I get complaints about 'missing $ inserted'.



beginequation labelPearson
begintabulary 18cmL R @ >$c<$ @ L
&Sim_a,b^PCC& = 
& $displaystyle frac
 sum_Pin P( r_a,p - overline ra)( r_b,p - overlinerb) %
 sqrtsum_Pin P( r_a,p - overlinera)^2
 sqrtsum_Pin P( r_b,p - overlinerb)^2$
endtabulary

    (1) Welcome, (2) full minimal example please. How are L, 'R` etc defined? NMormally these are lower case. (3) You have math in call 2, does R take case of this? Now you know why we always ask for a full minimal example that others can copy and test withoput adding anything or having to guess.

    tabulary is designed for tables with large amounts of text to adjust line breaking, you almost certainly should not be using it here at all, this seems to be a math alignment so align or aligned would be more suitable. the error is because you have math markup _ and ^ in the R column which is a text column.

    @daleif tabulary columns are LCR (but using `tabulary with math is somewhat strange!)

I can see no reason for employing a 4-column tabulary environment; an equation environment is all you need.



I would, though, replace all instances of overline with bar. And it should be sum_pin P rather than sum_Pin P, and barr_a and barr_b rather than barra and barrb, right?



If you have several equations which need to be aligned on their respective = symbols, do look into employing the align environment (provided by the amsmath package).

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala
